made me curious and I checked the data for M5. I thought some respectful tests done at the time would be more fair to judge the E60 M5 cause there are comparisons nowadays underlining how much better or faster the F10 is (by the way I personally couldn't like the new M5 much, I would take the E60) and I found that Autocar (I respect their detailed road tests) has some good data for the M5 from 2004 as well as their 2011 road test and data for the 1M. You can find both in internet easily and maybe u r already familiar with them so I am not attaching anything here. The relevant data is printed and sitting in front of me right now:
The acceleration: Till 60mph 1M is faster and they get even at 4.6s. at 60mph. After that slowly the M5 pulls away and the distance at 150mph is simply huge: the 1M reaches there at 31.3 sec. while M5 needs only 21 sec. Impressive stuff. Standing quarter mile 12.8 s. at 119 miles for M5 and 13.3 s. at 109 miles for the 1M.
In gear times: 1M better almost everywhere.
Brakes: 1M has better numbers.
There is more performance data about the 1M than the M5 and I think it is kind of natural that the 1M would post better times on almost any track which we already knew from the press but I conclude that probably you were more right than I was and an acceleration race between the two with pro drivers in both should finish in favour of the E60 M5 IF we are talking about a race continuing after the 60mph threshold on a long straight. In terms of performance that seems to be the only area that the E60 M5 has a clear upper hand over the 1M.
Yup, everything you state is true and credible. That was the point I was making, in a straight line race at best both are equal, we saw the 1///M handily walk the E60 M5 and increase that distance as the speeds got higher, which is where the M5 shines (big V10 lungs breathing vs. small turbos running out of breath). Hence why I felt something was amiss. Especially juxtaposed to the 1///M being beaten by the C63AMG which itself is beaten (straight line drag) by the M5. Trust me, I like nothing more than to brag that our beloved 1///Ms are faster on a straight unrestricted line than the V10 behemoths, but sadly they are not (up until the first left or right turn that is, he he)
